罐高小于16米：
The height of the tank is less than 16 meters.
1、那么先操作浮子（步骤见“浮子操作”），在操作指令中选择“BOTTOM LEVEL(罐底)”指令后按压“E”键确认，仪表的浮子将下降到罐底，此时请注意在该画面的最上部会显示16米倒计数，当浮子降到罐底后将停止；
1. Operate the float first (see "float operation"), select the "BOTTOM LEVEL (bottom of tank) command in the operation command and press the"E"key to confirm that the float of the instrument will drop to the bottom of the tank. At this time, please note that the 16-meter countdown will be displayed at the top of the screen, and stop when the float falls to the bottom of the tank.
2、按压“+”或“-”键选择“STOP”命令让浮子停下来，然后记下此时画面上部显示的数值，用16米减去该值即为仪表安装点到罐底的高度（即：罐高），或者通过多次按压“E”键直到画面显示静态矩阵“GVH=020  OPERATION”然后按压“—”键直到画面显示“Measured Value 1”（测量值 1），按压“E”键进入，第一个画面显示“液位高度”，继续按压“E”键第二个画面显示“空高”。
2. Press the "+" or "-" button to select the "STOP" command to stop the float, and then record the value displayed on the upper part of the screen at this time. Subtract the value by 16 meters, that is, the height from the instrument installation point to the bottom of the tank (i.e. the height of the tank), or press the "E" key several times until the screen shows the static matrix "GVH = 020 OPERATION" and press it. Press the -"key until the screen shows"Measured Value 1"(measurement value 1), press the"E"key to enter, the first screen shows"liquid level height", continue pressing the"E"key and the second screen shows"empty height".
记住这个值，这个值就是需要设定的罐高值（一般取比该值稍大几个毫米的整数值），然后多次按压“E”键返回（画面显示“Measured Value 1”（测量值 1）），多次按压“+”键直到画面显示静态矩阵“GVH=020  OPERATION”（功能组位置为GVH=020，操作），然后按压“E”键进入；
Keep this value in mind. This value is the tank height that needs to be set (usually a few millimeters larger than this value), then press the "E" key several times to return (the screen shows "Measured Value 1" (measurement value 1), press the "+" key many times until the screen shows the static matrix "GVH = 020 OPERATION" (functional group). Set it to GVH = 020, and then press the "E" key to enter.
3、按压“+”或“-”键选择“UP”命令让浮子上升到16米，后按压“+”或“-”键选择“STOP”命令让浮子停下来；
3. Press the "+" or "-" button to select the "UP" command to raise the float to 16 meters, then press the "+" or "-" button to select the "STOP" command to stop the float;
4、然后间断按压“E”键直到显示返回到“GVH=020  OPERATION”矩阵；
4. Press the "E" key intermittently until the display returns to the "GVH = 020 OPERATION" matrix.
